One of my least played genres because of the time investment required to get good.
But I did play Tekken 3, 4, and T2 and really enjoyed those. Got decently good with Hwoarang and Steve.
Street Fighter II Turbo was another favorite.
The only other fighting games I've played were Soulcalibur III, BlazBlue Continuum Shift Extend, Mortal Kombat Trilogy, and Evil Zone of all things. None of those really stuck.
